The problem is that neither windows nor OSX teach computing or computing culture. They teach the feudal model. The increasingly walled gardens. The "When in danger, when in doubt, run in circles, scream and shout" Currently Linux is the place where you can get your hands dirty and has the Wild West spirit that the 80s,90s and the internet had. We should teach the kids to spit in the face of authority and when obeying it to do it so reluctantly. And currently we are doing the exact opposite in all areas of human knowlege.
However they're just the foundations on which you teach. Programming languages, tools and software packages are the important bits. Which OS doesn't matter really. Neither does any red vs blue pill selection.
Most of my knowledge is applicable to any platform as it's fairly generic. I avoid specialisation for this reason.
I can sit down on any machine and be productive straight away regardless of if it's open source or a feudal empire. That's what we should be teaching.
